Sindri knew she would probably need to go home before following whatever... pull this was to find runes, doing whatever else the Mythris ancestors needed her help with. Cupid would be beside himself, and after all, Sindri hadn't even thought she'd be gone more than a day, let alone the several it'd taken to get to the mountain let alone the now trek home she had to take.
Perhaps he would be less angry, knowing she'd mostly been with Tyr. She doubted it, but there was always room for hope, right?

Well, Tyr was certainly mad. Though Sin had finally felt the spark of a connection with the chimera man, she recognized that he was notably and understandably a little... well, pissed off, short with her, quiet. So she respected that, letting the Big Feelings fade as they put distance between themselves and that prophetic cave. After a long, long time and a good sleep, she woke the next morning with plans to apologize again. She got up super early (before the sun! it was always hard to sleep at night, though she was doing her best to rest when Tyr told her to), and managed to chase down two pale hares.
The piebald runt hurried back with all the swiftness she had in her paws, noting the sun climbing the sky, and hoped Tyr was still asleep.

She offered a muffled woof as she drew nearer to where they'd bunked down.
